1. Basic form: For the basic form, Bootstrap did not do much customized effect design, only customized the fieldset, legend, and label tags in the form.
fieldset {
min-width: 0;
padding: 0;
margin: 0;
border: 0;
}
legend {
display: block;
width: 100%;
padding: 0;
margin-bottom: 20px;
font-size: 21px;
line-height: inherit;
color: #333;
border: 0;
border-bottom: 1px solid #e5e5e5;
}
label {
display: inline-block;
margin-bottom: 5px;
font-weight: bold;
}2. Horizontal form class name “form-horizontal”
##.form-horizontal .control-label,
.form-horizontal .radio,
.form-horizontal .checkbox,
.form-horizontal .radio-inline,
.form-horizontal .checkbox-inline {
padding-top: 7px;
margin-top: 0;
margin-bottom: 0;
}
.form-horizontal .radio,
.form-horizontal .checkbox {
min-height: 27px;
}
.form-horizontal .form-group {
margin-right: -15px;
margin-left: -15px;
}
.form-horizontal .form-control-static {
padding-top: 7px;
}
@media (min-width: 768px) {
.form-horizontal .control-label {
text-align: right;
}
}
.form-horizontal .has-feedback .form-control-feedback {
top: 0;
right: 15px;
}
Example1.Input box input: for To make the control style correct in various form styles, you need to add the class name "form-control". Each form control below can be added.
nbsp;html> <meta> <title>表单控件——输入框input</title> <link>
Example
Example
3.内联表单 类名“form-inline”
ea：添加了类名“form-control”类名，则无需设置cols属性。
示例
4.复选框checkbox和单选择按钮radio：水平排列加类名“checkbox-inline”||类名“radio-inline”
4.复选框checkbox和单选择按钮radio：水平排列加类名“checkbox-inline”||类名“radio-inline”
nbsp;html> <meta> <title>表单控件——表单控件大小</title> <link>
.radio,
.checkbox {
display: block;
min-height: 20px;
padding-left: 20px;
margin-top: 10px;
margin-bottom: 10px;
}
.radio label,
.checkbox label {
display: inline;
font-weight: normal;
cursor: pointer;
}
.radio input[type="radio"],
.radio-inline input[type="radio"],
.checkbox input[type="checkbox"],
.checkbox-inline input[type="checkbox"] {
float: left;
margin-left: -20px;
}
.radio + .radio,
.checkbox + .checkbox {
margin-top: -5px;
}
.radio-inline,
.checkbox-inline {
display: inline-block;
padding-left: 20px;
margin-bottom: 0;
font-weight: normal;
vertical-align: middle;
cursor: pointer;
}
.radio-inline + .radio-inline,
.checkbox-inline + .checkbox-inline {
margin-top: 0;
margin-left: 10px;
}5.控件大小：类名input-sm:让控件比正常大小更小；类名input-lg:让控件比正常大小更大；宽度配合Bootstrap的网格系统
.input-sm {
height: 30px;
padding: 5px 10px;
font-size: 12px;
line-height: 1.5;
border-radius: 3px;
}
select.input-sm {
height: 30px;
line-height: 30px;
}
textarea.input-sm,
select[multiple].input-sm {
height: auto;
}
.input-lg {
height: 46px;
padding: 10px 16px;
font-size: 18px;
line-height: 1.33;
border-radius: 6px;
}
select.input-lg {
height: 46px;
line-height: 46px;
}
textarea.input-lg,
select[multiple].input-lg {
height: auto;
}6.表单控件状态（焦点状态）：类名form-control
.form-control:focus {
border-color: #66afe9;
outline: 0;
-webkit-box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);
box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);
}7.表单控件状态(禁用状态)：form-control别忘记加①在需要禁用的表单控件上加上“disabled”；②fieldset设置了disabled属性，整个域都将处于被禁用状态。
.form-control[disabled],
.form-control[readonly],
fieldset[disabled] .form-control {
cursor: not-allowed;
background-color: #eee;
opacity: 1;
}8.表单控件状态(验证状态):1、.has-warning:警告状态（黄色） 2、.has-error：错误状态（红色） 3、.has-success：成功状态（绿色）
：需要类名has-feedback +
9.表单提示信息："help-block" 
.help-block {
display: block;
margin-top: 5px;
margin-bottom: 10px;
color: #737373;
}按钮

1.基本按钮：类名“btn”
.btn {
display: inline-block;
padding: 6px 12px;
margin-bottom: 0;
font-size: 14px;
font-weight: normal;

text-align: center;
white-space: nowrap;
vertical-align: middle;
cursor: pointer;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
background-image: none;
border: 1px solid transparent;
border-radius: 4px;
}2.默认按钮: 类名“btn” + 类名“btn-default” 
.btn-default {
color: #333;
background-color: #fff;
border-color: #ccc;
}
4.按钮大小: .btn-lg:大型按钮 .btn-sm:小型按钮 .btn-cs:超小型按钮
.btn-lg,
.btn-group-lg> .btn {
padding: 10px 16px;
font-size: 18px;
line-height: 1.33;
border-radius: 6px;

.btn-sm,
.btn-group-sm> .btn {
padding: 5px 10px;

.btn-xs,
.btn-group-xs> .btn {
padding: 1px 5px;
font-size: 12px;
line-height: 1.5;
border-radius: 3px;
}5.块状按钮: 类名“btn-block”
6.禁用状态: 使用disabled类或disabled属性
图像 1.img-responsive：响应式图片，主要针对于响应式设计 2.img-rounded：圆角图片 3.img-circle：圆形图片 4.img-thumbnail：缩略图片
img {
vertical-align: middle;
}
.img-responsive,
.thumbnail>img,
.thumbnail a >img,
.carousel-inner > .item >img,
.carousel-inner > .item > a >img {
display: block;
max-width: 100%;
